Changing the board to the divider bridge option

The BATT-14EXTENDER board offers the option to use an external power supply to power-up the EVBs. In this case, the user will have to populate the divider bridge with the appropriate resistors:

R1 to R14: 1 K recommended with a (1206) footprint
R15 to R16: 0 R with a (1206) footprint

The user will also have to populate the temperature sensor footprint RT1-RT4 with a (1206) NTC. For example, NC20K00103JBA from AVX.

Use case 1

In this use case, the BATT-14EXTENDER is powered up by a BATT 14CEMULATOR. Up to four EVBs can be connected to the BATT-14EXTENDER. No additional components need to be populated. The board is delivered by default for this use case.
Product Usage

Use case 2

In this use case, the BATT-14EXTENDER is powered up by a BATT 14EMULATOR and up to four EVB can be connected to the board. BATT 14EMULATOR doesn’t have an NTC emulation. In order to allow the EVBs to have an NTC emulation, it is recommended to populate RT1-RT4 footprints with NTCs.
Product Usage

Use case 3

In this use case, the BATT-14EXTENDER is powered up by an external power supply. The positive terminal of the power supply is connected to J7 and the negative to J8. J7 and J8 are 2 mm banana plugs.

Divider bridge resistors as well as NTCs must be populated to be able to use the board with that option.
Product Usage
